UF scientist says "clear evidence that much of the oil is still below the surface in subsurface plumes"

More damage may still occur as much of the oil has yet to be located in the Gulf.

“There is clear evidence that much of the oil is still below the surface in subsurface plumes,” said Tom Frazer, Associate Director of the University of Florida School of Forest Resources and Conservation Program in Fisheries and Aquatic Sciences.

“They are hard to quantify because when that water moves again, the rate of movement is something we don’t fully understand. We don’t know exactly where all of it is, but we are pretty sure that there is a fair amount of oil still on the bottom,” Frazer said.
